Lateral View Mandible and Molar Teeth of a Bear
Did you know that generally greater than 90% of a Black Bears diet comes from plants. Based on skull anatomy and phylogenetic history, bears are classified as carnivores but in terms of diet, bears are truly omnivorous (diverse diet of both plant and animal materials). Note that the molars of a bear are similar to human teeth in form and function and indeed man and bear have similar diets.
